Uarm won't calibrate

So I have assembled my uarm without any issues and uploaded the proper libraries into the arduino and uploaded them onto the uduino. When i power up the arm and hold D7 for 3 seconds I don’t get the beeps and cannot calibrate it or use the arms functionalities…
Did anyone run into this problem or know what I might have done wrong?

Hi, Which version of uArm do you have?
